Degrees Of Difficulty In Winter Weather

SIOUX FALLS, SD -
Even though temperatures started out in the single digits for some Monday morning, not everyone will be getting snow with the next storm system. That's because the difference of one degree can make all the difference when it comes to precipitation.
Tuesday's storm system will wrap in much warmer air from the south as is gets closer to KELOLAND. It won't necessarily be warm at the surface, but it will be much warmer 1,500 feet above the surface resulting in much of the precipitation falling in the form of rain for southeast KELOLAND.
Due to the last week's snow in southeast KELOLAND, it will take a while to warm the surface above freezing. Before that happens, the rain will freeze on contact with the surface. Just a couple hundredths of an inch of ice is all it takes to make things an icy mess. Some areas in the southeast can receive a couple tenths of ice.
Of course, where temperatures are cold enough to support all snow, beware of snow fall totals of more than eight inches. The best area to get the heavy snow is near and north of Highway 14.
